Question 1
What Mach number indicates that a flow can be considered incompressible?
- < 0.1
- < 0.3
- < 1.0
- < 2.0
💡 Hint: Remember the threshold for compressibility.
Question 2
True or False: Incompressible flow means the flow's density can change significantly.

Question 1
A tank with a diameter of 2 m is being filled with water at a rate of 0.1 m³/s. Calculate how high the water level rises in the tank after 10 seconds.
💡 Hint: Remember how to convert the volume into height using the tank's area.
Question 2
For a 0.5 m channel width carrying water at an average velocity of 2 m/s, calculate the flow rate. If the width increases to 1 m, what will the new flow rate be if the velocity remains the same?
💡 Hint: Flow rate changes linearly with the area and velocity.
